chemicals
Synthetic reactive substances
Chemicals are substances with distinct molecular compositions, especially those produced or used in industrial processes.
The word often carries connotations of artificiality or potential harm: The label says no artificial chemicals.
In casual use, chemicals suggests synthetic additives as opposed to natural ingredients, though technically everything material is chemical.
They tested the water for chemicals.
